BACKGROUND OF THE INVENTION

[0001] The present invention relates to a structure for combining a backpad and a bottom pad of a leisure chair, and especially to a leisurechair having the effect of being assembled and detached easily with lesstime and power. Moreover, the structure of the leisure chair isenhanced.

[0002] Whether a chair is comfortable is a main concern in the currenttrend since modern people spend many time to seat on a chair. Anuncomfortable chair will induce the ache of body so that one seating onthe chair will feel uneasy and thus the working efficiency is decreased.

[0003] The prior art leisure chair (referring to FIG. 1) is formed by aback frame, a bottom frame and legs. The back frame and bottom frame arefixed with a plurality of strips by riveting so that the plurality ofstrips may define the back pad and the bottom pad so as to provide theeffect of seating comfortably.

[0004] However, in assembling the leisure chair, the strips must beplaced to the back frame and the bottom frame one by one and then theyare fixed by riveting. Therefore, the assembly and detaching of theleisure chair are time and power consumed. The riveting fixing betweenthe back pad and bottom pad and strips, only point fixing is used sothat the combination is not steady. If the load on the strip is tooheavy, it is possible that the strip will break and the back pad andbottom pad can not be used.

SUMMARY OF THE INVENTION

[0005] Accordingly, the primary object of the present invention is toprovide a structure for combining a back pad and a bottom pad of aleisure chair having the effect of being assembled and detached easilywith less time and power. Moreover, the structure of the leisure chairis enhanced.

[0006] A structure for combining a back pad and a bottom pad of aleisure chair is disclosed. The leisure chair is formed by a back frame,a bottom frame, and a plurality of legs; a back pad and a bottom pad areformed on the back frame and the bottom frame. Supporting frames of theback frame and the bottom frame are formed with joint portions,respectively. The back pad and the bottom pad are pads of whole pieces.Two sides of the back pad and bottom pad have assembly portionsinstalled in the joint portions, respectively. By the assembly portionsat two sides of the back pad and the bottom pad passing through thejoint portions at two sides of the back frame and the bottom frame; theleisure chair has the effect of being assembled and detached easily withless time and power. Moreover, the structure of the leisure chair isenhanced.

[0007] The various objects and advantages of the present invention willbe more readily understood from the following detailed description whenread in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Referring to FIGS. 2, 3, 4 and 5, the perspective view of thepresent invention, exploded views of the back pad and bottom pad of thepresent invention, and a partial enlarged view of FIG. 4 areillustrated. The present invention relates to a structure of a leisurechair. The leisure chair is formed by a back frame 11, a bottom frame12, and a plurality of legs 13. A back pad 2 and a bottom pad 3 areformed on the back frame 11 and the bottom frame 12. The back pad 2 andthe bottom pad 3 may be pads fabricated by alternatively arranging aplurality of strips 14. The supporting frames 111, 111′, 121, 121′ ofthe back frame 11 and the bottom frame 12 are formed with joint portions112, 112′, 122, 122′. The joint portions 112, 112′, 122, 122′ aretrenches. The back pad 2 and the bottom pad 3 are pads of whole pieces.Two sides of the back pad 2 and bottom pad 3 have assembly portions 21,21′, 31, 31′ installed in the joint portions 112, 112′, 122, 122′. Eachof the assembly portions 21, 21′, 31, 31′ is formed by an enclosingportion 4 and a rod 41 matching to the enclosing portion 4. After theback pad 2 and the bottom pad 3 are installed on the back frame 11 andbottom frame 12. A plurality of supporting rods 113, 123 aretransversally installed at the proper positions of the back frame 11 andthe bottom frame 12 for enhancing the strength of the installed back pad2 and bottom pad 3. The plurality of supporting rods 113, 123 may beinstalled to proper positions of the back frame 11 and the bottom frame12 by the rivets 5. After assembly portions 21, 21′, 31, 31′ areinstalled to the joint portions 112, 112′, 122, 122′ of the back frame11 and bottom frame 12, one end of each of the supporting frames 111,111′, 121, 121′ of the back frame 11 and bottom frame 12 is added with aplug 6 for preventing the end surface formed by the assembly portions21, 21′, 31, 31′ assembled to the joint portions 112, 112′, 122, 122′from hurting the user, and moreover, the leisure chair has a beautifuloutlook. By the assembly portions 21, 21′, 31, 31′ at two sides of theback pad 2 and the bottom pad 3 passing through the joint portions 112,112′, 122, 122′ at two sides of the back frame 11 and the bottom frame12. The leisure chair has the effect of being assembled and detachedeasily with less time and power. Moreover, the structure of the leisurechair is enhanced.

[0014] Referring to FIGS. 3, 4, and 5, the exploded views of the backpad 2 and bottom pad 3 of the present invention and a partial enlargedview of FIG. 4 are illustrated. As illustrated in the figures, the twosides of the back frame 11 and bottom frame 12 of the present inventionare symmetric and have the same the way for installation. Therefore,only the part of bottom pad 3 are described herein with reference to theenlarged view. When installing the present invention, at first, theassembly portions 21, 21′, 31, 31′ at two sides of the back pad 2 andbottom pad 3 are aligned to the joint portions 112, 112′, 122, 122′ ofthe supporting frames 111, 111′, 121, 121′ of the back frame 11 and thebottom frame 12, and then one end of each of the assembly portions 21,21′, 31, 31′ at two side of the back pad 2 and bottom pad 3 are addedwith a plug 6 for preventing the ends surfaces of the assembly portions21, 21′, 31, 31′ assembled to the joint portions 112, 112′, 122, 122′through the rod 41 installed in the enclosing portion 4 from hurting theuser so that the leisure chair 1 has a beautiful outlook. Therefore, theleisure chair has the effect of being assembled and detached easily withless time and power. Moreover, the structure of the leisure chair isenhanced.

[0015] The present invention are thus described, it will be obvious thatthe same may be varied in many ways. Such variations are not to beregarded as a departure from the spirit and scope of the presentinvention, and all such modifications as would be obvious to one skilledin the art are intended to be included within the scope of the followingclaims.
